The Fire Department of the Village is hereby authorized and
permitted to go to the aid of another city, Village, town or fire
district or territory outside the Village to aid in extinguishing
a fire or fires therein, and while in the performance of their duties
in extending such aid, the members of said Department shall have the
same immunity and privileges as though performing the same within
the Village, pursuant to § 209 of the General Municipal
Law. The Chief or other head of the Fire Department, or of any company
thereof, is authorized to extend such aid, in his discretion, in answer
to a call for assistance from such village, town, fire district or
other territory, provided always that sufficient apparatus and membership
is kept in the Village for local protection at all times.
